英文摘要：

Cadherin is one of the most important receptors for crystal ingiensis in insects. The type, structure and distribution of cadherin toxins of Bacillus thur- in insects are sketchedThe binding sites of both crystal toxin and cadherin are discussed in depth. The mechanism of interaction of cadherin with crystal toxin of Bacillus thuringiensis is expounded in detail, and the relations betweeen cadherin and insect resisitance are also presented.
